community Did anybody use beta sisterol for hair loss? I saw in many articles in the internet that said that beta sisterol blocks dht by inhibiting 5a reductase type 2 enzyme and some reviews of people who said that it worked better than saw palmetto in terms of stoping hair loss and helping prostate.

in Research/Science 8 upvotes 2 years ago

Beta-sitosterol may inhibit 5-alpha reductase type 2 enzyme, potentially reducing DHT levels and promoting hair growth, similar to finasteride but possibly with fewer side effects. Its effectiveness and side effects compared to other treatments like saw palmetto and finasteride remain uncertain due to limited research.

community Trying to understand finasteride side effects and post finasteride syndrome

in Finasteride/Dutasteride 70 upvotes 5 years ago

The conversation discusses the side effects of finasteride, including low libido and erectile dysfunction, and the possibility of these effects being permanent, known as post-finasteride syndrome (PFS). Some users report personal experiences with PFS and debate whether the condition is real, with varying opinions on the reversibility of side effects and the role of individual biology.

community 3 month progress dut

in Progress 309 upvotes 6 years ago

User experienced rapid thinning on crown, used dutasteride for 3 months with significant improvement. Microneedling and ketoconazole were also used, but no minoxidil or finasteride.

community How come dutasteride doesn't lower allopregnanolone, but finasteride does?

in Finasteride/Dutasteride 11 upvotes 1 year ago

Finasteride significantly lowers allopregnanolone levels, while dutasteride's effect is less clear and may vary. Some users speculate that dutasteride might be healthier for the brain due to its different inhibition pathways.

community Study shows further evidence that finasteride and dutasteride take 12-18 months or more to show significant results. Do NOT give up early

in Finasteride/Dutasteride 247 upvotes 2 years ago

The conversation discusses the effectiveness of finasteride and dutasteride in treating hair loss, emphasizing that significant results often take 12-18 months or more. Dutasteride is generally considered superior, with similar or fewer side effects than finasteride, but patience is required for noticeable improvement.
